Title

Partial Shipment for Woocommerce <= 3.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Settings Modification via wxp_order_shipment, wxp_order_item_shipment, and wxp_order_set_shipped AJAX Actions

Summary

The Partial Shipment for Woocommerce plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.4 via the wxp_order_shipment, wxp_order_item_shipment, and wxp_order_set_shipped AJAX actions. This is due to the AJAX handlers in woocommerce-partial-shipment.php (registered at lines 60–62 and implemented at lines 228, 263, and 291) lacking both capability checks and nonce verification, and not validating the calling user's ownership of the supplied order_id. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary order item details (names, quantities, shipped counts) belonging to any customer and to modify the shipment status / shipped quantities of any order, which can also trigger order status transitions via the wxp_order_status action.

Severity

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
